Marriage data show a strong degree of positive assortative mating along a variety of attributes. But since marriage is an equilibrium outcome, it is unclear whether positive sorting is the result of preferences rather than opportunities. We assess the relative importance of preferences and opportunities in dating behaviour, using unique data from a large commercial speed dating agency. While the speed dating design gives us a direct observation of individual preferences, the random allocation of participants across events generates an exogenous source of variation in opportunities and allows us to identify the role of opportunities separately from that of preferences. We find that both women and men equally value physical attributes, such as age and weight, and that there is positive sorting along age, height, and education. The role of individual preferences, however, is outplayed by that of opportunities. Along some attributes such as occupation, height and smoking opportunities explain almost all the estimated variation in demand. Along other attributes such as age , the role of preferences is more substantial, but never dominant. Despite this, preferences have a part when we observe a match, i. Research home Research home.

Furthermore, even where a recognisable date is provided, it may not always be what it at first appears.

Climate change. Geology of Britain. We use a wide range of environmental agents for this work including CFCs, SF6, tritium, radiocarbon and stable isotopes. There are various reasons why it can be important to know the age of groundwater in a particular aquifer. For example: does age validate the hydrogeological concept? Is the water a mixture of different ages? Is the water sustainable or being ‘mined’?
Did the water recharge in pre-industrial times? Was the water recharged during the ice age, i. Some groundwater dating agents, for example radiocarbon 14C are produced naturally in the environment and are suitable for dating waters many thousands of years old. Others, such as the chlorofluorocarbons CFCs , are the result of man-made inputs to the environment and are best suited to dating young groundwaters.

In this article, an overview is presented of the status of the radiocarbon dating of iron-based materials. Recent advances include simplification in sample preparation and reduction in sample size for accelerator mass spectrometry measurements, and the potential use of rust as a viable source of material for radiocarbon dating. Additionally, a summary is presented of all 63 previously published results for iron-based materials and 29 new results that have not been published previously. These materials range from low-carbon wrought irons to medium to very high-carbon steels and cast irons.
